I support adoption of this draft, and I'm happy to help review it
and to make sure it's well synchronized with the hash-to-curve and
BLS signatures efforts (just as Armando has already said).

But I am a bit wary about mission creep. In particular I think we
should want pretty strong justification before adding specialized
constructions like the ZEXE curves and the Coda cycle. I'd prefer
for those to live in their own document(s) since probably they're
unnecessary (and add needless cost) for most applications.
